The Need For KB Analysis u Large-scale knowledge repositories will necessarily contain KBs produced by multiple authors in multiple settings u KBs for applications will typically be built by assembling and extending multiple modular KBs from repositories that may not be consistent u KBs developed by multiple authors will frequently u Express overlapping knowledge in different, possibly contradictory ways u Use differing assumptions and styles u For such KBs to be used as building blocks - They must be reviewed for appropriateness and correctness u That is, they must be analyzed
